Lithocolletis junoniella o£ Zeller (L. E., i, 215, fig. 20), and of Herricb- 

 Sehiiffer (v,329, fig. 770), which are identical with L. vacciniella, Stn. 

 The series of concomitella in the Douglas collection is still labelled 

 "'junoniella.''^ 



Stainton, Zool., 1851, App. clxx, proposed tentatively the name 

 " pomonella (dejlexella) " for what is now regarded as a variety of the 

 spring brood of spinicolella, Z. 



Steudel, JH. Ver. Nat. Wiirtt., xxxviii, 231 (1882), proposed the 

 employment of the same name {dejiexelld) for the similar variety of 

 '"'' pomifoUella" 



He also proposed (/. c. 232) the varietal name conjunctella, Stdl., 

 for the form of spinicolella in which the first and second dorsal teeth 

 unite to form an ai'ch. [== pomonella var. c, Z., L. E., T, 202, ante 

 241-242.— Dbnt.]. 



Sorhagen, Kleinschm. M. Brandenburg, 275 (1886), employed 

 the varietal name conjunctella for '"'' pomifoliella^'' as also for aii 

 alder-feeding species, probably alniella, 7i. ; he did not use it to indi- 

 cate the form desci'ibed by Steudel, but for that to which Stainton 

 had applied the name deflexella. 



Neither Steudel nor Sorhagen had any intention of naming 

 species ; they simply indicated the occurrence of parallel variation in 

 more species than one, giving to these homologous variations homo- 

 nymous names — a perfectly logical proceeding, but one which could 

 in no way affect special synonymy. 



It is obvious that a new name is wanted for the old " pomifoliella.'''' 

 For this species I propose the name concomitella {cum = with, comes 

 = a companion), because it is so often found, on the same apple trees, 

 in company wath blancardella, F.

* Duponchel's published figure more resembles pyrivorella, sp. n., but the original drawing, 

 now in the Merton library, proves that Duponchel's species is the one under notice.
